kernel versions

[wysiwyg]

Good morning all!  Over the last several releases I have noticed that the Linux kernels being created for TC appear to be random version numbers instead of LTS.  For example, the latest version is 4.2.9, but the latest LTS is 4.1.18.  I was just wondering why these kernel versions were being used instead of ones listed as long term.

Thanks,
Dave

4.2 is an Ubuntu LTS. https://lkml.org/lkml/2015/12/15/538

Hey Curaga!

Hmmm that's interesting.  So TC uses the kernel source from Ubuntu?  Any idea why that's the case?  Kernel.org (which is who I would assume TC would mimic) doesn't show that as LTS at all.  Doesn't that make TC dependent on Canonical for patches to their selected LTS kernel?  Wouldn't it be safer to have the larger community support using official LTS kernels?

It makes little difference since Core almost never updates a kernel within a major release.

I guess that's true since TC doesn't have any LTS releases itself.  I was thinking beyond just TC (e.g. forks or users that can't update for some reason), but thanks for the tip gerald_clark!

Canonical's kernel engineers have access to the exact same resources as Greg and other kernel.org stable maintainers, as well as additional pressure from the Ubuntu release using it. Thus I don't see the Canonical dependency as a risk.
